Product Introduction
ANSI standard bushings are transformer bushings manufactured in accordance with the American National Standards Institute (ANSI) specifications - a key compliance component for entering the North American market. In North America, transformer manufacturers and utilities commonly require bushings to meet the ANSI standard series, ensuring that electrical performance and mounting dimensions fully match existing equipment in the market, enabling safe and reliable operation as well as convenient interchangeability for maintenance. ANSI standard bushings are widely applied in oil-immersed distribution and power transformers, performing the core functions of carrying winding leads through the tank wall while providing insulation to earth and firm mechanical support - indispensable components in North American grids, substations and industrial power distribution projects. Choosing ANSI-compliant bushings helps customers avoid compliance risks, shorten project acceptance cycles and ensure long-term stable operation of equipment.
The manufacturing process of ANSI standard bushings starts with high-grade electrical porcelain materials, going through batching, forming, drying, glazing, high-temperature firing, machining and metal part assembly. The porcelain body is produced from high-alumina electrical porcelain formulas, formed by isostatic pressing or slip casting with precise trimming, coated with a uniform glaze layer and then fired in a high-temperature kiln, giving the body excellent dielectric and mechanical strength. After firing, the end faces and mating surfaces are precision ground to ensure accurate mounting dimensions. The aluminum flange is produced by casting and machining, and securely assembled with the porcelain body through reliable cementing or sealed mounting; the conductive rod is inserted and sealing components are installed. Before delivery, every bushing undergoes electrical tests and dimensional inspection in accordance with ANSI requirements, ensuring stable performance and reliable interchangeability in installation..
Accurate technical drawings are the core basis for bushing selection and transformer design. The outline dimensions, flange mounting dimensions and electrical parameters of ANSI standard bushings must match the transformer tank interface precisely - any deviation in drawings may affect installation efficiency or even cause rework on site. Therefore, we provide complete technical drawings for each ANSI standard bushing, including outline dimension drawings, installation dimension drawings and flange drilling details, in PDF and editable formats (such as DXF/DWG) for customer selection and design reference. Meanwhile, our engineering team offers full technical guidance: assisting customers in confirming installation solutions, reviewing customer-supplied drawings, and producing bushings per drawings to ensure a seamless fit with your transformer design.
This product covers several specifications and models - the table above lists some of them for selection reference, covering different voltage ratings, rated currents and flange mounting dimensions to flexibly suit oil-immersed transformers of various capacities and structures. For selection, please match the transformer's rated voltage, rated current and tank mounting hole dimensions against the parameters in the table to confirm the required specification. If the required specification is not listed, we support customized production per drawings and technical requirements - our engineering team will first confirm the mounting interface and electrical parameters to ensure a perfect match with your design. Detailed parameters are subject to the final confirmed product specification; please feel free to contact us for complete selection documentation or technical consultation.
